ABOUT
the project
The Federal Highway Administration (FHWA) Central Federal Lands Highway Division, in cooperation with the Hawaii Department of Transportation (HDOT), is partnering together to support the HDOT’s goal of maintaining and improving the state’s highway infrastructure. The Hana Highway Bridge Improvements project is evaluating six bridges along the Hana Highway (State Route 360) for potential improvement.
Overall Purpose
The overall purpose of the project is to improve six bridges (view map) in a context-sensitive manner so they are safe and functional for highway users. Goals for the project were established based on public and agency input during the development of the 2015 Hana Highway, Route 360 Bridge Preservation Plan.
